Ingress of Sea Water into Closed-Cell Polymeric Foams Data and Observations

2 Ingress of Sea Water into Closed-Cell Polymeric Foams Data and Observations 

Earlier data on the uptake of sea water were collected for Divinycell HlOO and H200 closed-cell PVC foams (Li and Weitsman 2004). Weight gains were recorded periodically for samples of thicknesses varying between 2 and 9 mm that were immersed in sea water at room temperature for more than 2 years. In addition, expansional strains were measured periodically and microscopic observations of fluid-induced damage were taken intermittently.

8 Sea Water Effects on Foam-Cored Sandwich Structures 

Typical observations of sea water-induced damage are shown in Figs. 8.1-8.3. Weight gain data are exhibited in Fig. 8.4a, b, with data scatter indicated by vertical bars.
